FLY-TRAP.

Specification of Letters Patent.

Application filed March 31, 1913.

Patented Sept. 2,1913.

Serial No. 757,921.

To all whom it wm concern Be it known that 1, Louis C. Aonnn, a citizen of the United States, residing at Stanford University, in the county of Santa Clara and State of California, have invented a new and useful Improvement in Fly- Traps, of which the following is a specification.

My invention relates to an improvement in fly-traps.

One objectof my invention is to provide an inconspicuous and easily adjusted flytrap that can ladjusted to any window, and is especially designed for use in oliice, shop and store windows.

Another object of my invention is to provide a lly-trap that can be adjusted directly to a glass window pane, and consequently will not interfere with the placing of goods in a show window.

Fl'u'ther objects and advantages will appear in the following description.

I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a perspective view of the flytrap attached to a window pane. Fig. 2 is a vertical cross-section on line A--A of Fig. 1.

Similar numerals refer to similar parts throughout the several drawings.

In the drawings here presented, 1, Figs. 1 and 2, is a watentight sheet-metal receptacle of the required dimensions, having a bottom 2 designed to rest in an approximately horizontal position; a front 3 preferably inclining inwardly, and having its upper edge turned inwardly and clownwardly a distance as shown at 4, Figs. 1 and 2, for the purpose of preventing flies and insects caught in said receptacle from crawling up and over said edge and thus escaping; a back 5, Figs. 1 and 2, inclining outwardly for the purpose hereinafter specified, having its upper edge turned imvardly and downwardly a distance as shown at (3, Figs. 1 and 2, for the purpose of preventing flies from crawling up and over said edge and thus escaping; and two sheet-metal ends, 7 and 8 respectively, shown in Fig. 1, soldered to said bottom 2, front 3 and back 5, thus making a water-tight sheet-metal receptacle as shown. At each end of said receptacle 1 is attached an adjustable rod as shown at 9, Fig. 1, adjusted by means of a binding nut 10, which turns on threaded pin 11, which is soldered or fastened to the end of receptacle 1, as shown at 1.2, Fig. 1. This adjustable rod 9 is for the purpose of developing to the fullest the suction properties of suction disks 13, shown in Figs. 1 and 2, and forcing the lower edge of said receptacle 1 away from the window pane shown at 'l=.l-, and :loreing the upper edge of said back 5 of receptacle 1 snugly and firmly against said window pane 1 1. Said rubber suction disks 1? are glued or otherwise fastened by their tips to said back 5 of re ceptacle l, and constitute the means whereby said rcccptacle is attached to window pane l-il. In using my device, the receptacle 1 is placed in position at the lower end of window pane til; the back 5 of said receptacle 1 is then pressed against said window pane 1-1, which causes said rubber suction disks '13 to take hold of said window pane 14; the adjustable separating rods S) are then adjusted as described, drawing the upper edge of said back 5 of receptacle 1, snugly against said window pane 14: as described. The fly catching liquid or other suitable material is then placed in said receptacle, and the trap is ready for use. W'hile a water-tight receptacle is described in the above specification, I do not wish to confine myself to this particular kind of reccptaclc,-as all or parts of it may be made of wire netting or other suitable material, and paper or fabric coated with a sticky substance placed therein to catch the flies.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

In a fly-trap, the combination of a. re ceptaclc of any suitable size or shape adapted to hold a fly destroying substance or fly catching device, having two or more of its upper edges turned inwardly and down wardly a distance. a plurality of rubber suction disks attached to one side of said receptacle, and an adjustable separating rod attached to each end thereof, substantially as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
